Adam hasn't ruined everything. Not yet. But Wading River native Adam Conover continues to give it his best as he debunks widely held myths and common misconceptions in the new season of "Adam Ruins Everything," premiering Tuesday at 10 p.m. on truTV.

This season also ups the ante on guest stars. While name actors like "Frasier" star Peri Gilpin and comedians Mo Gaffney, Larry Hankin and John Michael Higgins have appeared on the quirky little educational-comedy show, the new season offers stand-up star Whitney Cummings, song parodist "Weird Al" Yankovic and singer Lance Bass.

Yankovic, he says, "was one of my personal heroes growing up and I'm so thrilled. We asked and he immediately said yes. That's why we're in L.A. — because people say, 'Oh, you're shooting in [easily accessible] Burbank? Sure, I'll show up.' "
